Explanation:
Part A
In the bright daylight, the Calvin cycle happens indoors in the stroma. throughout the Calvin cycle, the results ATP and NADPH are conventional convert molecules of carbonic acid gas into high-energy sugars.
Part B
In the darkness, the Calvin cycle conjointly occurs within the stroma. through the Calvin cycle, the products ATP and NADPH are used to change molecules of CO2 into high-energy sugars.
Part C
There will be a decrease in the products ATP and NADPH if the plants are unbroken within the dark for a protracted time and also the Calvin cycle can't be sustained.
The correct answer is A. Lac repressor.
Lac repressor prevents lac gene which are found in the DNA of Escherichia Coli from being expressed for many times.
Lac repressor is termed as DNA which binds proteins. It allows the expression of genes from coding which are made for proteins to be involved in metabolism of lactose which is in bacteria.
When there is no lactose which is available in the cell, then the genes are being repressed. Lactose are being converted to allolactose if they are available.
